Tsunami warnings were issued for the North Coast, the Haida Gwaii islands, parts of the central B.C. coast, the coast of Alaska and as far away as Hawaii.

Early Sunday morning the warnings were downgraded to advisory status, meaning evacuations were no longer necessary, and they were cancelled altogether a few hours later.

Residents near the centre of the quake said the violent jolting lasted for up to a minute, but no injuries or major damage had been reported.

Carsten Ginsburg, who lives in the small community of Bella Coola southeast of Prince Rupert, said the quake lasted about 40 seconds.

“It shook everything. The electricity went out, the power lines were swinging all over the place and stuff was falling off the shelves.”

Brent Ward, an earth scientist at Simon Fraser University, said the earthquake was the second largest to hit the country since 1949, when another earthquake was recorded in the same area with a magnitude of 8.1.

“It’s an earthquake in an area that gets a lot of earthquakes,” he said. “It’s a tectonically active area.”

Ward said the area is known as the Queen Charlotte fault, where the earth’s plates slide horizontally across each other in a strike-slip action, similar to what happens along California’s San Andreas fault.

“Stresses build up because of that movement, and every so often we get the release of that stress in the form of an earthquake.”

Ward said he wasn’t surprised the tsunami warning was shortlived because the strike-slip movement along the fault doesn’t generally trigger tsunamis.

“To trigger a tsunami you need to have a vertical movement of the sea floor, and it’s that vertical movement that displaces water and triggers the tsunami,” he said. “Because it’s sliding across each other, you’re not generally moving the water.”

In fact, hours after the earthquake, Dennis Sinnott, who works at the Institute of Ocean Sciences, said the largest wave hit Langara Island, a northern Haida Gwaii island, and measured just 69 centimetres.

The quake also set off emergency sirens across the Pacific on the islands of Hawaii, but even as people were moving to higher ground, the warning was called off.

In Alaska, the wave surge was just 10 centimetres, much smaller than officials had been forecasting.

Kelli Kryzanowski, manager of strategic initiatives Emergency Management B.C., said the initial earthquake occurred at 8:04 p.m. inland on Haida Gwaii and was initially recorded at a magnitude of 7.1 but was quickly upgraded to a magnitude of 7.7.

Kryzanowski said small waves generated by the quake, measured at 28 centimetres and 44 centimetres, also hit the northern tip of Vancouver Island.

“What we’re seeing at this time are relatively small sea-level fluctuations,” she said.

B.C. Justice Minister Shirley Bond said there appeared to be little damage from the quake.

“We’re certainly grateful at this point,” said Bond, who spoke to reporters during a late night conference call. “We’re very grateful for that, but we’ll wait until we can actually see the impact.”

After the quake, Ginsburg said he ran home as quickly as he could to see if there was a tsunami warning.

“Which of course there was,” he added.

Ginsburg owns the Float House Inn on the public wharf in Bella Coola and had about six customers celebrating a birthday party.

Cornish lives in a log house and had been told that it’s one of the safest places to be in the event of an earthquake.

But she said it sure didn’t feel safe Saturday night.

“The log house swayed and creaked and my light over my kitchen table was swaying, some chimes went off. I stood up and I could feel the undulations under my feet, to the point where I almost got nauseated.”

Geoff Ray said he has felt a lot of earthquakes, but this was the most powerful quake he’s ever experienced in the 37 years he’s lived on Haida Gwaii.

Ray operates the Breezeway Accommodations bed and breakfast in Queen Charlotte City and said the beams of his building were “visibly shaking quite a lot, there were things falling off shelves.”

“(It was) an exciting experience, there’s no doubt about that.”

Lenore Lawrence, a resident of Queen Charlotte City, said the quake was “definitely scary,” adding she wondered if “this could be the big one.”

She thought the shaking lasted more than a minute.

While several things fell off her mantle and broke, she said damage in her home was minimal.

Residents rushed out of their homes in Tofino when the tsunami sirens sounded, but they were allowed to return about two hours after the quake.

Yvette Drews, a resident of Tofino, said she ran out of her home with her two children and mother in-law and drove to a local school when she heard the community’s tsunami sirens go off.

They were told by police that they could return home.

But while on the way home, Drews said she heard the tsunami sirens go off again.

“Well that just freaked me out, hearing the siren and the voice,” she said.

The quake shook Vancouver Island, the Haida Gwaii area, Prince Rupert, Quesnel and Houston, and was even felt in Metro Vancouver and Alaska.

“It’s a good wake-up call for everyone to make sure they have an earthquake kit and a plan if an earthquake like this hits an area that they live,” said Ward.
